이하, 상기한 구조를 갖는 본 발명의 일 실시예에 따른 디스플레이장치(100)의 작용 및 효과를 설명하면 다음과 같다.Hereinafter, the operation and effects of the display device 100 according to an embodiment of the present invention will be described.

본 발명은 카지노용 모니터에 적용되는 디스플레이장치(100)에 관한 것으로, 사용자의 시각을 이끌기 위해 가장자리 전후에 빛을 조사하여 시각적 효과를 구현할 수 있다.The present invention relates to a display device (100) applied to a monitor for a casino, and a visual effect can be realized by irradiating light before and after the edge to lead a user's view.

먼저, 본 발명에 따른 디스플레이장치(100)의 조립을 살펴보면, 프레임(110)의 측면 둘레를 따라 광원(142)이 구비된다. 광원(142)은 플랙시블 PCB(143)와 LED(144)로 이루어져 프레임(110)의 측면에 고정되며, 플랙시블 PCB(143)는 굴절되어 컨트롤부(미도시)와 전기적으로 연결된다. 이러한 구조는 협소한 공간의 활용도를 향상시킬 수 있으며, 컴팩트한 제품을 제공할 수 있다.Referring to the assembly of the display device 100 according to the present invention, a light source 142 is provided along the side surface of the frame 110. The light source 142 is composed of a flexible PCB 143 and an LED 144 and fixed to the side surface of the frame 110. The flexible PCB 143 is refracted and electrically connected to a control unit (not shown). Such a structure can improve the utilization of narrow space and can provide a compact product.

이후, 광가이드바(145)를 프레임(110)의 관통홀(112)을 통해 관통시키고, 프레임(110)부의 전측에 글라스부(130)를 고정한다. 광가이드바(145)의 선단은 글라스부(130)의 가장자리 내면에 접하게 된다. 그리고 프레임(110)의 배면에 배면커버(120)를 결합한다.Thereafter, the light guide bar 145 is passed through the through hole 112 of the frame 110, and the glass part 130 is fixed to the front side of the frame 110. The tip of the light guide bar 145 is brought into contact with the inner surface of the edge of the glass part 130. Then, the back cover 120 is coupled to the rear surface of the frame 110.

이때, 광가이드바(145)의 선단 외측에는 확장부(146)가 형성되고, 확장부(146)는 배면커버(120)의 단턱부(125)와 일치되어 글라스부(130)와 배면커버(120) 사이에 개재되어 고정된다. 즉, 광가이드바(145)는 선단은 확장부(146)에 의해 고정되고, 후단은 프레임(110)의 관통홀(112)과 배면커버(120)의 개구홀(122)에 의해 지지되어 고정됨으로써, 별도의 체결부재 없이 광가이드바(145)를 고정할 수 있다.The extended portion 146 is formed on the outer side of the front end of the light guide bar 145 and the extended portion 146 is aligned with the step portion 125 of the rear cover 120 to connect the glass portion 130 and the rear cover 120, respectively. The rear end of the light guide bar 145 is supported by the through hole 112 of the frame 110 and the opening hole 122 of the rear cover 120 to be fixed The light guide bar 145 can be fixed without a separate fastening member.

이처럼, 디스플레이장치(100)의 시각적 효과를 내기 위한 엣지라이트부(140)가 글라스부(130)의 외부에 별도로 구비되지 않고, 내부에 일체로 구비됨에 따라 컴팩트한 구조를 지님은 물론, 미감을 향상시킬 수 있다.Since the edge light unit 140 for providing the visual effect of the display device 100 is not separately provided outside the glass unit 130 but is integrally provided inside the glass unit 130, the edge light unit 140 is not only compact, Can be improved.

엣지라이트부(140)에 의해 작용을 설명하면, 전원의 인가에 의해 광원(142)이 발광하면, 프레임(110)의 측면으로 조사되는 빛은 광가이드바(145)를 통해 디스플레이장치(100)의 전측과 후측으로 빛을 조사할 수 있다. 광가이드바(145)는 우유빛을 갖는 플라스틱재질로 이루어져, 빛을 확산하고, 전후측으로 안내하여 은은한 빛을 낼 수 있으며, 협소한 공간으로 인한 광원(142)의 핫스팟(hot spot) 현상을 방지할 수 있다.When the light source 142 emits light by application of a power source, the light emitted to the side of the frame 110 passes through the light guide bar 145 to the display device 100, The light can be irradiated to the front side and the rear side. The light guide bar 145 is made of a plastic material having a milky light, and diffuses light, guides the light to the front and rear sides to emit a gentle light, and prevents a hot spot of the light source 142 due to a narrow space can do.

이때, 광가이드바(145)의 둘레면에는 화이트반사판(147)이 구비되어 광원(142)에서 조사되는 빛의 손실없이 정확하게 전후측으로 안내할 수 있다.At this time, a white reflection plate 147 is provided on the circumferential surface of the light guide bar 145 so that it can be accurately guided to the front and rear without loss of light emitted from the light source 142.

광가이드바(145)를 통해 전측으로 안내되는 빛은 빛번짐방지부(150)에 의해 보다 선명에서 전측으로 조사될 수 있어 미감을 향상시킨다. 빛번짐방지부(150)는 화이트마스크(152)와 블랙마스크(154)로 이루어져 빛의 명암비를 향상시킨다. 또한, 후측으로 안내되는 빛은 개구홀(122)을 통해 노출된 후단을 통해 외부로 조사되어 디스플레이장치(100)의 후광을 구현할 수 있어 미감을 향상시킨다.The light guided to the front side through the light guide bar 145 can be irradiated from the clear to the front side by the light blur prevention unit 150, thereby improving the aesthetics. The light blur prevention unit 150 includes a white mask 152 and a black mask 154 to improve the light contrast ratio. In addition, the light guided to the rear side is irradiated to the outside through the rear end exposed through the opening hole 122 to realize the backlight of the display device 100, thereby improving the aesthetics.

이러한 후광은 디스플레이장치(100)의 후측에 구비되는 별도의 기구물이나 벽면에 반사판을 구비하여 무드등으로 활용될 수 있다.The backlight may be a separate device provided on the rear side of the display device 100 or a mood or the like by having a reflector on the wall.

상기한 바와 같이 본 발명의 일 실시예에 따른 디스플레이장치에 의하면, 글라스부의 내부에 일체로 광원의 빛을 안내하는 광가이드바가 구비되어 전면과 후면에 시각적 효과를 주어 미감을 향상시킬 수 있으며, 측면으로 조사되는 빛을 광가이드바에 의해 안내하므로 컴팩트한 구조를 지닐 수 있다.
As described above, according to the display device of the embodiment of the present invention, a light guide bar for guiding the light of the light source integrally in the inside of the glass part is provided to improve the aesthetics by giving a visual effect to the front and rear surfaces, So that light can be guided by the light guide bar and thus can have a compact structure.
